The Warmer Homes Scheme can provide free energy-efficiency improvements for eligible homeowners who receive certain qualifying social welfare payments. Eligibility may also depend on factors such as when the home was built, whether it is your main residence and the outcome of a home energy assessment. There is generally no charge for approved works under the scheme, but applying does not guarantee that upgrades will be offered or that every improvement will be covered. SEAI makes the final decision, so check the current criteria on the official SEAI website before applying.
